I mean "native" in terms of what's supported by the language itself, out of the box.

C and C++ offer -at a minimum- the following numeric types:

* signed and unsigned integers in a variety of widths

* 32 and 64-bit floating point numbers

JavaScript offers:

* 64-bit floating point numbers

When performing integer math, JavaScript's numeric type is only safe for arithmetic operations between -((2^53)-1) and +((2^53)-1).

Now that we have that out of the way, my original question remains unanswered. :)
